INT 3C - FLOATING POINT EMULATION - INSTRUCTIONS WITH SEGMENT OVERRIDE Notes: the floating-point emulators in Borland and Microsoft languages and Lahey FORTRAN use this interrupt the generated code is CD 3C xy mm .... where xy is a modified ESC instruction and mm is the modR/M byte. The xy byte appears to be encoded as s s 0 1 1 x x x or s s 0 0 0 x x x where "ss" specifies the segment override: 00 -> DS: 01 -> SS: 10 -> CS: 11 -> ES: SeeAlso: INT 3B,INT 3DTop
